Rewriting history?

I very often update and modify my posts until I feel they carry the meaning I intended. With English being a foreign language to me, there are many instances where my posts end-up being interpreted the wrong way or don't represent my message really well.

I'll be migrating this blog over to my own servers quite soon, and I've been wondering if all those edits should be done the way they are now, without history, or if I should adopt a more bliki approach and leave anyone to see the variations and edits I do on posts.

Does historic truth matters to you? Do you want to see my edits? Or do you only care about the end result?
